| 20110075313 | PLASMA ARRESTOR INSERT - A dielectric arrestor insert for use in a chamber wafer processing system having a gas input line, an arrestor housing and a wafer processing space. The input line is able to provide gas to the arrestor housing. The arrestor housing is able to house the dielectric arrestor insert. The dielectric arrestor insert comprises a gas entry portion, a non-linear channel and a gas exit portion. The gas entry portion is arranged to receive the gas from the input line. The non-linear channel is arranged to deliver the gas from the gas entry portion to the gas exit portion. The gas exit portion is arranged to deliver the gas from the non-linear channel to the wafer processing space. | 2011-03-31 |

| 20110075315 | ECONOMIZER FOR VEHICLE BATTERY DISCONNECT - An economizer configured to connected coils in series and in parallel with a voltage source in order to facilitate pulling relays to a closed position, and thereafter, holding the relays in the closed position while reducing a voltage applied across the coils. | 2011-03-31 |
| 20110075316 | SYSTEM FOR RECOVERING AND USING THE ELECTROSTATIC CHARGE GENERATED BY LIGHTNING - A system for the recovery and use of the electrostatic charge present in the atmosphere during storms generated by lightning, transforming natural energy into electrical energy useful for consumption, and providing the necessary protection for lives and property against electro-atmospheric phenomena, has an ecological lightning conductor, an electrical conductor connected by one end to the low-frequency electrode of the lightning conductor, and an enhanced intelligent earth wire, whereto the conductor is joined by its other end. The conductor includes a series of probes and magnetic field detectors which will send information to the microprocessor and from there to the mainframe computer. The control device allows regulation of the earth resistance, thereby generating more or less charge, diverting the energy to the accumulators or to earth through dissipator electrodes. | 2011-03-31 |
